Here is a suggestion as to what to look for. It is working for me, maybe it will for you. This is just a very thin outline......
1. Check your region for manufacturing companies. Decide whether or not there is an opportunity for exploiting those products on the market via the internet.
2. If there is an opportunity available, research and pick up a relevant domain name. Approach the manufacturing company with information regarding wholesale pricing, and any drop ship programs they may offer. See if they will drop ship with no markings, or your markings.
3. Build a web site with a fairly focussed range of products. You may have to stock some items, but they may be willing to drop ship larger ones for you.
4. Go to shareasale.com and create a merchant program. This will cost a couple hundred bucks, but will also give access to their affiliates, who will be willing to resell all of your products for you, for a decent commission.
5. Start developing an affiliate base, a core group of active affiliates.
6. Once that particular niche business is profitable, move on to your next local manufacturing company.
You can find one list of manufacturing companies from the
Thomas Register I'm sure there are other directories as well you can look in.
You can also look for distributors, fairly easy to find, for just about every line of products you can find.
